Description

Technical Field

[0001] The utility model relates to the technical field of structural ceramics, in particular to a mixing device for preparing super-wear-resistant MAX phase ceramics for automobile gears. Background Art

[0002] MAX phase ceramics are a type of ternary carbon / nitride ceramics with a nano-layered structure. MAX phase ceramics have the characteristics of both ceramics and metals, such as high strength, high electrical and thermal conductivity, corrosion resistance, oxidation resistance, and excellent machinability. They are now used in the manufacture of gear materials for certain automotive assemblies.

[0003] When preparing MAX phase ceramics, powders such as Ti2AlC, Nb2AlC and Cr2AlC are uniformly mixed in a certain proportion, and the MAX phase sintering mixed powder is obtained after ball milling and drying. Since dry powders of various specific gravities are mixed, the degree of mixing is more difficult than liquid mixing, and the mixing time is longer. Utility Model Content

[0004] In order to solve the problems of insufficient dry powder mixing and long mixing time during the preparation of MAX phase ceramics, the utility model provides a mixing device for preparing super wear-resistant MAX phase ceramics for automobile gears.

[0005] The technical solution provided by the utility model is: a mixing device for preparing super-wear-resistant MAX phase ceramics for automobile gears, comprising a mixing tank, a stirrer and a feed port are arranged on the mixing tank, a discharge door is arranged at the lower part of the mixing tank, a guide tank is welded at the bottom of the mixing tank, the guide tank is a cup-shaped structure, a guide seat is installed at the lower part of the guide tank, the guide seat is a cup-shaped structure, the cup wall at the upper part of the guide seat is matched and connected with the outer circle guide of the guide tank, a motor is installed at the cup bottom of the guide seat, an eccentric cam is installed on the output shaft of the motor, and a compression spring is installed between the bottom of the guide tank and the cup bottom of the guide seat.

[0006] A bottom skid is installed at the bottom of the guide seat, and a limit tube is welded on the bottom skid. The inner hole of the limit tube is larger than the outer circle of the guide seat. A hydraulic cylinder is installed on the other side of the discharge door of the bottom skid. The hydraulic cylinder is installed vertically, and a baffle is welded above the plunger of the hydraulic cylinder on the guide seat.

[0007] The beneficial effects of the utility model are as follows: the mixing tank and the guide seat are elastically connected. When powders are mixed, the stirring paddle of the stirrer stirs while the motor drives the eccentric cam to make the mixing tank vibrate up and down, thereby eliminating the problem of uneven mixing of powders of different specific gravities in the height direction. After the mixing is completed, the plunger of the hydraulic cylinder lifts up one side of the mixing tank, the mixing tank is at a certain inclination angle, the motor is turned on to vibrate the mixing tank, and the powder in the mixing tank is completely discharged without residue.
